If you need to block a member or MV Star from viewing your profile, live room or from sending you messages, there are two ways to do this.
The first way to block another user is from that users profile. To do so, click the 3-dots in the top right of their profile and select <Block>.
The other way to block a user is from the drop-down menu > My MV > Security Center. Find the section named “Blocked Members / MV Stars” and click <View>, enter the username of the user you wish to block and hit “Block”.
To unblock a previously blocked user, go to your drop-down menu > My MV > Security Center and click <View> next to "Blocked Members / MV Stars". Locate the user you wish to unblock and click the <X> next to their username, click <Yes> and they are now unblocked.
